5-1/2"(140MM) 180SC FLEX HONE - Brush Research

The Brush Research GBD51218 5-1/2" (140MM) 180SC FLEX HONE is a professional-grade honing tool engineered to deliver superior surface finishes and deburring capabilities for automotive and industrial applications. This heavy-duty flexible hone is designed for meticulous professionals who require precise bore conditioning, contributing to enhanced component performance and longevity. Its unique design ensures self-centering, self-aligning, and self-compensating for wear, producing a consistent, oil-retaining cross-hatch pattern on various metal surfaces.

Key Features

• 5-1/2" (140mm) Diameter: Provides extensive contact area for efficient and thorough bore finishing in larger components.
• 180 Grit Silicon Carbide Abrasive: Features a hard, sharp, and durable silicon carbide abrasive, ideal for honing mild steel, stainless steel, and cast iron, while producing a smooth finish.
• Flexible Design: Conforms seamlessly to internal bore contours, effectively removing peaks and imperfections to create a true plateau finish.
• Heavy-Duty Construction (GBD Series): Built with a longer abrasive section, making it suitable for demanding, large-diameter, and high-production applications.
• Optimized for Oil Retention: Creates a consistent cross-hatch pattern crucial for maintaining proper lubrication and sealing, reducing friction and wear.

Applications

This versatile tool is essential for professional technicians and mechanics across various demanding sectors. It is commonly used for deglazing and surface finishing engine cylinders, preparing them for new piston rings and ensuring optimal oil control and reduced blow-by. The GBD51218 is also highly effective for honing brake cylinders, valve guides, and other hydraulic components to ensure superior sealing and operational efficiency. Furthermore, its robust design is well-suited for industrial applications such as finishing and deburring bores in hydraulic cylinders, ram cylinders, and valve bodies, as well as maintaining critical components in marine engines and oil and gas piping.
